    • A filter for CATV applications includes a housing and two interface caps, each with an annular groove in a header portion thereof. A circuit board having a grounding bus along an edge of the board is disposed inside the housing. A split ring grounding clamp is disposed inside the housing such that a plurality of split rings are adjacent the grounding bus. The interface caps are press fitted into the ends of the housing, forcing the plurality of split rings into uniform contact with the grounding bus. The ends of the housing are then crimp-rolled such that a ridge is formed in the housing where the grooves in the headers are located in the interface caps, thereby sealing the ends of the housing to the interface caps.
    • 用于CATV应用的滤波器包括壳体和两个接口盖,每个接口盖在其头部中具有环形槽。 具有沿着板的边缘的接地总线的电路板设置在壳体内。 开口环接地夹设置在壳体内部,使得多个分裂环邻近接地母线。 接口盖压配合到壳体的端部,迫使多个分裂环与接地母线均匀接触。 然后将壳体的端部卷曲,使得在壳体中形成脊,其中集管中的凹槽位于接口盖中,从而将壳体的端部密封到接口盖。
